A particle starts its motion from rest under the action of a constant force. If the distance covered in first `10 s` is `s_1` and the covered in the first `20 s` is `s_2`, then.

A

`y=2x`

B

`y=3x`

C

`y=4x`

D

`y=x`

Text Solution

Verified by Experts

The correct Answer is:
C

`A` to `B: x=1/2a(10)^(2)`
`A` to `C: y=1/2a(10+10)^(2)`
`y/x=4impliesy=4x`
